AIMH040-1000A-420

Current Sensors Overview

The AIMH040-1000A-420 is a Hall effect current sensor module manufactured by Aim Dynamics. It features a single channel with unidirectional measurement capability and a single pass-through design. The device supports a maximum input current of 1000 A. It operates on a supply voltage of ±15 V with a maximum supply current of 35 mA. The output signal is ratiometric, ranging from 4 mA to 20 mA. The unit provides an accuracy of ±1% and functions within an operating temperature range of -10°C to 85°C.

Current Sensors Feature Summary

• Utilizes Hall effect technology for electrical isolation and current measurement
• Provides a standard 4-20 mA ratiometric analog output signal
• Features a split-core or single pass-through module design for easy installation

Current Sensors Applications

• Industrial power monitoring systems
• Battery management applications requiring high-current DC measurement
• Motor drive control circuits

Current Sensors Procurement Notes

Verify the specific model suffix to confirm unidirectional operation, as Aim Dynamics offers bidirectional variants within the same series. Ensure the required supply voltage matches the ±15 V specification. Confirm that the 4-20 mA output aligns with the receiving system's input requirements. Check that the 1000 A rating covers the peak load currents in the target application.

Current Sensors Selection Notes

Select this component when a unidirectional measurement up to 1000 A is required. The 4-20 mA output is suitable for long-distance transmission in industrial environments. Consider the ±15 V supply requirement during power budgeting. Verify that the operating temperature range of -10°C to 85°C meets environmental conditions. Compare against the 5V output series if voltage signaling is preferred over current loop.

Current Sensors Part Context

This part belongs to the AIMH040 series of Hall effect current transducers from Aim Dynamics. The series includes variants with different output types, such as 5V and 4-20mA, and both unidirectional and bidirectional configurations. The 1000A designation indicates the maximum measurable current capacity for this specific module.

Current Sensors Replacement Considerations

Direct substitutes include other Aim Dynamics models like the AIMH040-1000A-420B, though the 'B' suffix typically denotes a bidirectional variant which may not be functionally equivalent for unidirectional-only applications. Cross-manufacturer replacement requires matching the 4-20mA output, 1000A range, and ±15V supply constraints.
